Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede Airworthiness Directive (AD) 2018-26- 07, which applies to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2018-26-07 requires repetitive greasing of the thrust reverser actuators (TRAs), dispatch restrictions, and maintenance procedure revisions. Since we issued AD 2018-26-07, we are now proposing to add a requirement to replace the TRAs, which AD 2018-26-07 specified was not required at the time to provide the opportunity for the public to comment on the merits of that action. This proposed AD would require actions specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. We are proposing this AD to address the unsafe condition on these products.
